8 Claims. (Cl. 68-184) This invention relates to apparatus useful in treating continuous sheet or strand materials, such as textile fabrics, yarns and the like, with dyes, sizing or other liquids, or other liquids for the removal of extraneous matter.

The chief aim of my invention is to provide an apparatus for the above purpose which is simple in construction; which can be relied upon to effect thorough penetration of the materials by the liquids; and which is highly efficient both from the standpoints of output and of power consumption.

How the foregoing objects and advantages are realized in practice will appear from the following detailed description of the attached drawings, wherein:

Fig. 1 is a view, in longitudinal section, of an apparatus for liquid treatment of sheet or strand materials conveniently embodying my invention in one form.

Fig. 2 is a cross section of the apparatus.

Fig. 3 is a perspective view showing a modification of one of the component parts of the apparatus; and

Fig. 4 is a sectional view similar to Fig. 2 showing an alternative embodiment of the invention.

With more specific reference, first more particularly to Figs. l3 of these illustrations, the character 10a designates a trough for a treating liquid L, said trough having longitudinal side walls 11a which converge downwardly, a fiat bottom 12a, and end walls 13a and 14a.

Disposed lengthwise within the trough 10a and substantially submerged in the liquid L is a horizontallyarranged hollow immersion roll 15a which is open at its ends as at Ma, and of which the shell is perforated as at 17a. At opposite ends, the roll 15a is provided with trnnnions 18a and 19a respectively. As shown, the trunnion 18 is rotatively supported in a bearing 20a in the end wall 13a of the trough 10a, and the trunnion 19a, extends through and beyond a bearing 21a in the other end wall of the trough for connection thereto of a drive wheel or pulley 22a.

The continuous material M to be treated is directed into the trough 10a over a guide roll 25a so as to underpass the immersion roll 15a and, upon emerging from the liquid L, is directed over another guide roll 26. The rolls 25a and 26a are suitably journaled in the end walls of the trough, and it is to be noted that they are so spaced relative to each other and to the immersion roll 15a that the material M is caused to round the greater portion of the cylindrical surface of the latter roll while submerged in the liquid.

Overlying the immersion roll Ida in the interval between the guide rolls 25a and 26a is a bafiie in the form of a. bar 27a which is fixedly supported between the opposite end Walls of the trough, and of which the bottom surface is rounded concentrically with the immersion roll 15a and is spaced from the surface of the latter by a narrow working clearance 28a.

The trunnions 18a and 19a of the immersion roll 15a are hollow for journalling of the .opposite ends of the shaft 31 and 32 of a spiral having oppositely pitched end 15a is rotated in the. direction of the arrow in Fig. 2, I

As shown, the end 32 of the shaft protrudes beyond the end of the trunnion 19a of the immersion roll 15a and is there provided with a separate drive wheel or pulley 33. By reason of the described construction, it will be seen that, as the immersion roll treating liquid is drawn into the roll at opposite ends by the oppositely pitched sections 29a and 30a of the spiral, and expelled by Way of the perforations 17a to pass through the material M. At the same time, the material is eased slightly away from the surface of the immersion roll 15a by the pressure of the liquid which is thus universally distributed to insure thorough penetration-and saturation of the material. During the processing, a bafiie 27a obstructs the perforations in the upper exposed portion of the immersion roll to prevent the im pelled liquid from being squirted out of the trough by the action of the spiral. This construction is particularly advantageous when heavy liquids are employed which are thus more thoroughly and eifectively agitated for maintenance in homogenous condition. It is to be understood that the immersion roll 15a and the spiral are driven independently as indicated by the arrows in Fig. 2. This construction is advantageous over that shown in Figs. 1 and 2 when heavy liquids are employed which are thus more thoroughly and effectively agitated for maintenance in homogenous condition. It is to be understood that in this instance, the immersion roll 15a and the spiral are driven independently as indicated by the arrows in Fig. 2.

In Fig. 3, there is shown a modified form of immersion roll 15]) which, if desired or found to be more advantageous, may be substituted for the immersion roll in either of the two aforedescribed embodiments of the invention. Here, the roll 15b has, in its shell, circumferentially and longitudinally spaced horizontal slits 17b instead of round perforations, the slits of alternate longitudinal lines being staggered in relation to the slits of the intervening lines.

In the alternate embodiment illustratedin Fig. 4, the trough llc is wider than the trough of the previous embodiment and disposed in it, in parallel relation, are two open-ended hollow immersion rolls 15c and 35. The roll 15c is apertured as at 17c and provided internally thereof with a spiral 300. The second roll 35 is identical and apertured as at 37 and likewise provided internally with a spiral 39. In this instance, the material M to be treated is passed down into the liquid L under a submerged guide roll 250, then in succession about the perforated rolls 35 and and is finally withdrawn from the trough beneath another guide roll 260. It is to be noted that the guide rolls 25c and 260 are so located as to predetermine travel of the material substantially about the full circumferences of the rolls 15c and 35. Due to the provision of two perforated immersion rolls and contact of opposite faces of the fabric respectively with said rolls, the treating liquid is forced through the fabric in opposite directions by the action of the spirals 30c and 39 with assurance of thorough penetration of the liquid through the fabric. The baffles shown at 27c and 40 serve, like the bafiie of the previous embodiment, as shields over the exposed surface portions of the rolls 15c and 35. In the apparatus of Fig. 4, the trunnions of both rolls 15c and 35 may be solid as in Fig. 3, or one of the trunnions of each may be made hollowas in Fig. 3 for passage of the shafts 32c and 42 of the spirals 30c and 42 to the exterior and application of driving pulleys to them respectively.

Although in Fig. 4 I have shown but two roll spiral units, I do not consider myself so limited since three or en new 7 3 even m of such we ma 3?; tilised t ease 9? found to be advantageous.
